20mm Planetary DC Gear Motor Model NFP-20GP-180-EN

Permanent Magnet DC Hall Encoder Planetary Reduction Motor Parameters

Product Overview

The NFP-20GP-180-EN is a DC planetary gear motor with a Hall encoder. Therefore, it is suitable for motion systems that need speed feedback, direction control, and stable torque output.

In addition, this motor supports 6V DC and 12V DC versions. As a result, users can choose a suitable voltage for different control boards and power systems.

Moreover, the AB dual-phase Hall encoder can connect to an MCU. Therefore, users can build a closed-loop control system more easily.

Main Features

• All-metal gears: The gearbox uses metal gears. Therefore, it can support better wear resistance and longer service life.
• Pure copper winding: The rotor uses pure copper wire. As a result, the motor can provide better conductivity and stronger torque.
• Graphite carbon brush back cover: The back cover uses shockproof glue. In addition, this helps improve stable operation.
• Hall encoder feedback: The AB phase encoder outputs square wave signals. Therefore, users can read speed and direction with an MCU.
• CW and CCW rotation: The motor supports forward and reverse rotation. Moreover, this helps fit two-way drive systems.
